Abstract:
The present-invention relates to optical elements comprising fluorochemical surface treatments. The invention further relates to materials such as retroreflective sheetings, pavement markings and beaded projection screens comprising a binder and the surface treated optical elements.
Abstract:
Polymerizable fluorinated polyethers are formed by Michael-type addition of a reactive fluorinated polyether to a poly(meth)acryl compound. The polymerizable fluorinated polyethers may be used to form composite articles.
Abstract:
The invention features a coating composition that comprises a non-urethane acrylate or methacrylate compound in combination with a fluorochemical. Typically, the non-urethane (meth)acrylate is an aliphatic or aromatic (meth)acrylate compound and the fluorochemical typically comprises a monofunctional (per)fluoropolyether (meth)acrylate compound. The coating compositions can provide a protective topcoat layer to a variety of substrates, including wood and vinyl.
Abstract:
A flooring substrate comprising a coating of a curable composition that comprises (a) a reaction product of (i) a polyisocyanate, (ii) one or more perfluoropolyether compounds having at least one hydroxyl group and (iii) an organic compound having one or more free radical polymerizable groups and at least one hydroxyl group; and (b) a compound capable of free radical copolymerization with the reaction product and comprising at least two free radical polymerizable groups.
Abstract:
The invention relates to display and protective articles having a fluorochemical surface layer, and methods of making such articles. The invention also relates to fluoropolyether acrylate compositions.
Abstract:
A hard coating composition for use as a stain repellent single layer on an optical display. The coating composition adds a monomer of a mono or multi(methyl)acrylate bearing at least one monovalent hexafluoropolypropylene oxide derivative and a free radically reactive compatibilizer consisting of either a fluoroalkyl-group containing acrylate compatibilizer or a fluoroalkylene-group containing acrylate compatibilizer to a conventional hydrocarbon-based hard coat formulation. The resultant coating is substantially smooth and forms a durable surface layer that has low surface energy that is stain and ink repellent.
Abstract:
The present invention relates to optical elements comprising fluorochemical surface treatments. The invention further relates to materials such as retroreflective sheetings, pavement markings and beaded projection screens comprising a binder and the surface treated optical elements.
Abstract:
The invention features an article comprising a reactive substrate that forms a covalent or hydrogen bond with a surface layer. The surface layer of the article comprises the reaction product of at least one monoterminated (per)fluoropolyether (meth)acryl compound and at least one monomer or oligomer having at least two (meth)acryl groups.
Abstract:
The invention relates to articles such as protective films and displays having a fluorochemical surface layer comprising an antistatic agent and the reaction products of at least one fluoropolyether (meth)acryl compound and at least 50 wt-% of non-fluorinated crosslinking agent(s).
